PUMP.

SPECIFICATION forming part of Letters Patent No. 421,415, dated February18, 1890.

Application filed March 5, 1889- .To all whom it may concern:

Be it known that I, JOSEPH MENGE, a citizen of the United States,residing in the city of New Orleans, parish of Orleans, State ofLouisiana, have invented a new and useful Single-Piston Rotary'Pump, ofwhich the following is a specification. 1

My invention relates to improvements in single-piston rotary pumps, inwhich arotary piston is placed at the bottom of a pumpbox, and therevolving of same forming a suction draws in the water and forces sameup into the pump-box to the discharge-opening; and the objects of myinvention are, first, to provide means by which the rotary piston isprovided with a suction in both sides, thus placing the rotary piston inequilibrium; second, to provide means by which the driving-shaft androtary piston can be adjusted fromtop of pump-box. I attain theseobjects by the mechanism illustrated in the accompanying drawings, inwhich- Figure 1 is a vertical section of pump on plane N N, Fig. 5. Fig.2 is a vertical section of pump on plane V V, Fig. 5. Fig. 3 is ahorizontal section on plane S S, Figs. 1 and 2. Fig. 4 is a horizontalsection on plane X X, Figs. 1 and 2. Fig. 5 is a plan view of top of mypump.

Similar figures refer to similar parts throughout the several views.

The pump-box may be constructed of either wood or iron. If of theformer, the construction consists of four corner-posts, to which the boxsides 2 are secured, which sides are of tongued-and-grooved flooring.These sides 2 extend from the bottom up to and above thedischargeopening 1 9. The posts 1 extend above'the sides 2 to receivethe timbers 3 for the support of upper end of driving-shaft 4. Thedriving-shaft 4;, to which is secured the rotary piston 5 anddriving-pulley 6, rests in step 7, secured to the timber 8, placed inbottom of pump-box, This driving-shaft 4 extends the whole length ofbox, and is guided by the journal-boxes 9, 11, and 20. The bearing 11 isformed with a central recess 18, to serve as an oil-well, and the floorof which serves as a bearing for the lower end of the adjustable collar12 on the driving-shaft, secured thereto by means of a set-screw a. Bymoving the collar on the shaft and securing Serial No. 301,987. (Nomodel.)

it at the required line the shaft maybe used in boxes of differentheights, or the variances of wear compensated for.

Near the bottom of the pump-box is placed a tight floor 14, in which iscut a circular opening 15, directly under the rotary piston 5, whichforms the bottom suction. The water reaches this suction from the bottomof box and through the openings 16.

On top of the rotary piston and running across the pump-box is placed atight box or suction 10, with a circular hole 17 in the bottomof box,directly over the rotary piston 5, as shown. This box or suction 10 iscut through the sides of pump-box and receives the water to form the topsuction. A vertically-arranged plank 18, provided with a beveled edge,is placed and secured in diagonally-opposite corners of pump-box and atthe bottom of box. A flooring 21 is placed on an incline between thisplank 18 and sides of pump-box, as shown in Fig. 4 and in dotted linesin Fig. 1. The plank 18 cuts the rotary motion imparted to the water bythe turbine 5, and the momentum caused by thus breaking the rotarymotion assists to elevate the water up the inclined flooring 21 to theupper part of pump-box.

The operation of the pump is as follows: The pump-box, fitted up asdescribed and shown, is set into the water to a depth to cover theopenings into the upper suctionbox 10, when the box is thoroughly bracedand connected to motor by belt running on the pulley 6, which revolvesthe rotary pis ton 5, which produces a vacuum, and the water rushes intothe rotary piston through the circular suction-openings 15 and 17, andthe water is forced up into the pump-box until it reaches thedischarge-opening 19, where it is conducted to point desired by pipe orflume.

I claim as new and desire to secure by Letters Patentv 1. Inasingle-piston rotary pump, the combination, with the pump-casing havinga circular opening in the bottom, of the rotary pis ton mounted 011 avertical shaft over the said opening in the casing, a suction-boxarranged over the rotary piston and having a circular opening in itsbottom, inclined floorings arranged in diagonally-opposite corners ofthe pump-box, and vertically-arranged deflectin planks secured to theinner sides of the inand inclined water-ways arranged in diagoclinedfloorings, substantially as described. nally-opposite corners of thepump-box and 2.
